Suction bottle for medical purposes particularly for the connection of drainage tubes

Abstract

The closure part is formed by a flat plug which is longitudinally displaceable within a nipple of the suction bottle, the flat plug being displaceable from its basic position on the outside of transverse openings of the nipple, past the transverse openings, into its closing position just in front of the inner end of the nipple, in which closing position it is located at a greater distance from the transverse openings than the length between an end edge and sealing place of a drainage-tube connecting plug serving as a ram for the flat plug.

I claim: 
     
       1. In a suction bottle for medical purposes, and particularly for the connection of drainage tubes, having a valve located in the drainage path, a closure part which can be brought into an open position and a vacuum indicator, the improvement comprising a flat plug constituting the closure part,   a nipple communicating with an interior of the suction bottle, said nipple being formed with transverse openings and having an inner end,   said flat plug being disposed longitudinally displaceable within said nipple of the suction bottle, said flat plug being displaceable in said nipple, from a basic position thereof on the outside of said transverse openings of the nipple whereby the transverse openings communicate via said nipple with the interior of the suction bottle, inwardly past said transverse openings into a closing position just in front of the inner end of said nipple,   a drainage-tube connecting plug removeably positioned in said nipple and having a sealing place sealingly engaging said nipple and an end edge constituting a ram for pushing said flat plug inwardly into said interior of the suction bottle,   said flat plug in said closing position being located at a greater distance from said transverse openings than the distance between said end edge and said sealing place of said drainage-tube connecting plug.   
     
     
       2. The suction bottle according to claim 1, wherein said connecting plug defines an axial hollow,   the valve in the drainage path for a drainage tube is disposed in said axial hollow.   
     
     
       3. The suction bottle according to claim 2, wherein the valve is formed of a tube section closed at an end thereof and formed with longitudinal slots, said tube section constitutes a coupling piece between said connecting plug and the drainage tube.   
     
     
       4. The suction bottle according to claim 3, wherein said tube section has an intermediate section of a cross-section widened in the form of a plug.   
     
     
       5. The suction bottle according to claim 1, wherein said nipple has an inner wall,   said inner wall is stepped down in different diameters, becoming smaller in the inwardly direction towards said inner end of said nipple.   
     
     
       6. The suction bottle according to claim 1, further comprising a closure cap of the suction bottle,   said nipple projects at a top of said closure cap of the suction bottle and defines therearound with said closure cap an annular groove,   a suction head means releaseably sealingly disposed in said annular groove and for suction evacuation communication with said transverse openings and via thereby with the interior of the suction bottle, said suction head means includes a ram means for pushing said flat plug inwardly into said nipple into said closing position after the evacuation communication.   
     
     
       7. The suction bottle according to claim 1, further comprising a closure plug means for being removeably sealingly disposed in said nipple and extending therein to above said transverse openings and coordinated with an outside end of said nipple.   
     
     
       8. The suction bottle according to claim 1, further comprising a vacuum indicator constituting a bellows is mounted on said drainage-tube connecting plug.   
     
     
       9. The suction bottle according to claim 8, wherein said bellows is mounted in a transverse position on said drainage-tube connecting plug.   
     
     
       10. The suction bottle according to claim 8, further comprising an additional bellows is mounted on said flat plug.   
     
     
       11. The suction bottle according to claim 8, wherein said bellows has a connecting insertion collar communicating therewith and extending through said flat plug communicating with the interior of the suction bottle.
